Chemistry

<u>Answer:</u>

Sodium atom is larger than Magnesium atom.

<u>Explanation:</u>

Looking at the electronic configurations of Sodium and Magnesium:

_{11}Na: 1s^2 2s^2 p^6 3s^1\\\\_{12}Mg : 1s^2 2s^2 p^6 3s^2 ,

we can see that they both have their valence electrons in the 3rd shell.

But because Magnesium has a higher nuclear charge of +12 because of its 12 protons than that of Sodium's +11, the nucleus of Magnesium attracts its outer electrons more strongly than Sodium does. This makes the Magnesium atom smaller.
